SIP H' ON.I

SPECIFICATION forming part of Letters Patent No. 478,108, dated July 5,18912."

Application filed March 17, 1892.

To all whom it may concern.-

Be it known that I, JACOB HILDITcII, a citizen of Norway, residiug atOhristiania, in the county of Christiania, Norway, have invented certainnew and useful Improvements in Siphons; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, which form a part of'thisspecification.

My invention relates to means for securing siphons in bottles of anyordinary form, and at the same time simplifying and improving theconstruction thereof by reducing the number of parts, thereby reducingthe cost of manufacture.

The invention consists in the arrangement and combination of the partsthereof, as well as in the construction of the same, substantially ashereinafter described, and illustrated in the accompanying drawings, inwhich- Figure 1 is a longitudinal section of a siphon-bottle,illustrating one form of my invention. Fig. 2 is a modification of thesame; and Figs. 3, 4, and 5 show different means for attaching thesiphon to the bottle.

As shown in Fig. 1, A designates a bottle of a well-known form,'havingscrew-threads p formed on the inside of its mouth for receiving thescrew-threads on the outer periphery of the plug or stopper P, which hasan annular flange p formed thereon, and in the under surface of said.flange is formed a groove 0" to receive a ring or packing R, formed ofrubber or any equivalent material, thus insuring a perfectly air-tightstopper.

The plug or stopper P is provided with an exhaust-tube S, which may forman integral part thereof or may be soldered or otherwise securedthereto, said tube S having the spout 8, formed above the mouth of thebottle and at right angles thereto. In the upper end of the tube S is anopening through which the valve-stem T passes, said opening being madeair-tight by the insertion of an elastic plug or packing r, seated in aconical recess on the top of said tube, over which a washer 0 or cap 0,as shown in Fig. 2, is placed and forms a Serial to. 425,290. (Nomodel.)

bearing for the spiral spring 0, mounted on the valve-stem, which springbears upward against the knob t on top of the said valvestem. Thus itwill be readily seen that as the knob t is presseddownward the spiralspring 0 bears upon the washer 0, which rests on the elastic packing 0",thereby compressing the latterand completely closing the opening aroundthe valve-stem at the moment the valve at the bottom of the tube isopened to allow the fluidto pass out through the discharge-spout.

On the lower end of the stem T is secured the elastic valve-plug V bymeans of a disk or washer o. This valve-plug is shown conical in form,the face of which bears against the beveled end of the tube S; but itmay be made in any desired shape to form a perfectlytight joint.

' In Fig. 2 I have shown the pipe S made separate from the plug orstopper P, fitting over ashort tube 8 made thereon, with the valve Vbearing against the end of the short tube 8, thereby reducing the lengthof the valvestem. The placing of the valve V within the tube S wouldnecessarily require the diameter of the said tube to be made greater;but

this-I overcome by bulging the tube, as at a.

In Fig. 3 I have shown the plug P, provided with flanged projections aa, over which pass the wires B, formedwith books I) b, saidwires beingsecured to the neck of the bottle by a band or wire 0 and lockedtogether above the projections a a by the loop 0.

Fig. 4 shows a plate adapted to fit over the siphon-pipe and bearupon arubber ring or packing, said plate" being provided with slots a 0/ forthe reception of the swinging bolts B, which are locked to said plate bythe nuts I); and in Fig. 5 is shown a siphon-pipe inserted through acork. and held therein by means of a concave collar d, the edge of Whichis pressed into the cork,'which latter may be held in the bottle in theusual way by means of wire.

It will readily be seen that with the described construction anextremely simple and also very cheap siphon may be constructed that hasadvantages over other and more complicated siphons heretofore employed.

Having thus described my invention, what bearing-plate 0 forsimultaneously compressing the packing and operating the valve to allowthe d scharge of liquid, as set forth.

2. In a siphon attachment, a siphon-pipe having near its upper end anenlarged portion it, in combination with a discharge-pipe I 5 extendinginto said enlarged portion not the siphon-pipe, said discharge pipehaving a flanged enlargement adapted to be secured in the neck of thebottle, and a valve-stem having at its lower end a valve adapted toseat; 20

in the corresponding end of the dischargepipe, as set forth.

In testimony whereof I afiix my signature in presence of two witnesses.
